Enhancement of a UASB-septic tank performance for decentralised treatment of strong domestic sewage
The possibility of enhancing the process performance of the UASB-septic tank for treating strong sewage in Palestine by means of inoculating the reactor with well adapted anaerobic sludge and/or adding a packing media to the upper part of the reactor, creating an anaerobic hybrid (AH)-septic tank, was investigated. To achieve these objectives, two community onsite UASB-septic tank and AH-septic ...

Use of domestic sewage effluent for sustainable production of vegetable in Kashmir valley
Trace metals in discrete portions of knoll kohl were evaluated along with chemical composition of sewage effluent, irrigation water, and soil. High nutrients, Fe and Mn levels were noticed in the sewage effluent, whereas irrigation water showed recommended norms. Knoll kohl grown on sewage-irrigated soil accumulated sufficiently good amount of trace metals available to consumers. This study also ...

Design principles to achieve a robust sewage treatment process using rotating biological contactors and reed beds
Severn Trent Water Ltd. has chosen to adopt rotating biological contactors (RBCs) and reed beds amongst other technologies for treating sewage where the population is less than 2000. The design of an RBC to achieve a fully compliant effluent can be difficult when flows are small or the system is combined and an overflow is not permissible. In addition, RBCs have been plagued by mechanical ...
